Article Synopsis
- The study aimed to investigate how different patterns of blood flow in the kidneys, assessed through Doppler ultrasound, can indicate the severity of venous congestion and predict kidney function impairment in patients suffering from acute decompensated chronic heart failure (ADCHF).
- Conducted on 75 ICU patients, the study analyzed the blood flow patterns (normal, biphasic, monophasic) and measured sodium concentration in urine after diuretic treatment to monitor kidney injury and other complications.
- Results revealed that patients with a monophasic blood flow pattern had a significantly higher incidence of acute kidney injury (100%) and were more likely to experience in-hospital death and diuretic resistance compared to those with normal or biphasic patterns
This study's objective was to evaluate the effects of pharmacokinetic and pharmacogenetic factors on major bleeding in patients with ACS and non-valvular AF receiving combined antithrombotic therapy consisting of rivaroxaban, clopidogrel, and aspirin as part of dual or triple therapy. A prospective observational study was conducted in two PCI centers in Moscow, the Russian Federation, from 2017 to 2018. One hundred patients with ACS and AF were enrolled.

This is demonstrated for Si(553)-Au as a model system by combining density functional theory simulations and reflectance anisotropy spectroscopy experiments. We find that controlled H passivation is a two-step process: step-edge adsorption drives excess charge into the conducting metal chain "reservoir" and renders it insulating, while surplus H recovers metallic behavior.

A crude extract of Chl a was measured as a 1 × 10 mol/L ethanol solution (which represents an upper limit of concentration without aggregation) and as dried droplets. For the first time, the investigation of Mg bound to Chl a in a liquid environment by means of X-ray absorption spectroscopy is demonstrated.
